Lightweight and fast AMQP (0-9-1) server

I'm surprised that a few quick and obvious searches doesn't turn up an obvious LavinMQ vs. RabbitMQ direct comparison (other than the featured result, a terrible Medium post that looks like an LLM wrote it). I see lots of "LavinMQ is/does this!", but not "and this is how it's different from RabbitMQ..."

Can anyone point out a resource?

Slightly OT:

Are ZeroMQ and NanoMQ still widely used (and recommended)?

https://github.com/zeromq/libzmq

https://github.com/nanomq/nanomq

https://lavinmq.com/ and https://lavinmq.com/blog/lavinmq-next-gen-message-broker (history, reason for existence)

oh, interesting, so it can be a kafka replacement: https://github.com/cloudamqp/lavinmq/tree/v1.2.10#stream-que...

(it's Apache 2)

As I understand it Kafka was high-throughput/high-latency, whereas MQ (at least RabbitMQ) is the opposite - low-throughput/low-latency.

So they're solving different problems (streaming vs. message delivery)
